I believe I have nabbed the bug!! It was trying to read traffic stats from a non-existent VPN slot as it got killed... and became a big fat null. Let's see how this performs for you!As soon as the VPN client 1 connection displays info on page 2 of RTRMON, kill the VPN client connection via router web GUI — I see the two errors until page refreshes and removes VPN info. Turn it back on, waitt for VPN info to populate, rinse, and repeat.
